Hi,
We have an HP Proliant server, Win2K Server installed, Exchange 2000 Server SP3, with latest security patches and hotfixes applied.
This server is Domain Controller of Active Directory domain and serves the global catalog.
Every user which has an emailaccount can send email to internal users but also to every domain outside the company. => Local mailing + Internet mail.
Now I want to create some new users which should only have the possibility to send email to local users and NOT to send internet mail.
Can someone tell me how to do this ? Or explain which settings need to be adjusted or filled in.

PS : How can I change settings from existing users to restrict them also not to send internetmail.
NOTE : this should not be applied to all users, only to certain users.

One method is by only using X400 types of email addresses, thus stopping the user from sending and receiving internet mail. Another method is by setting up an SMTP Connector to the address space of *, and blocking the user from sending mail through it.

I take the no tolerance approach. Way i see it, is if you were having problems with certain users, compromising email policys or messing about on the net, just simply disable there access 2 all these things. I'm sure those who work especially, in education will agree...

I created smtp connector, address space = * and specified in the field REJECTED USERS : the userid of that user which isn't allowed to SEND EXTERNAL mail (= internet email)
Log off useraccount &amp; re-log on.. did the test.. user is still able to SEND external mail.

Where can I specify that 1 specific user (from Act.directory) is not allowed to SEND emails to the internet.
Same question for RECEIVING mail from the internet !

As you explained previously, which I've also tested succesfully, it's possible to restrict users from sending and/or receiving internet mail according to their group membership.
I wonder if it is also possible to restrict these users so that they only can send and receive email from 1 or 2 domains (for example : *.COM) but not to other domains.
